DUBAI: Kuwait said on Friday an Iranian attack damaged a desalination plant.

The attack came after an oil refinery was hit by drones on Friday morning.

Kuwait said without elaborating that the attack on the desalination plant caused “material damage to some of the plant's components.”

Desalination provides the majority of the water for the Gulf Arab states and Iran, drawing the salty waters of the Persian Gulf into drinking water for the desert region.

About 90 per cent of drinking water in Kuwait comes from desalination.

Desalination plants have become a major target in the war, with Iran initially accusing the US and Israel of striking one before beginning to target them in the Gulf Arab states. Those states view attacks on desalination plants as a threat to their very livelihoods.
